Smart Grid and Renewable Energy (SGRE) , 2012, DOI: 10.4236/sgre.2012.34045
Abstract: In the framework of liberalized deregulated electricity market, dynamic competitive environment exists between wholesale and retail dealers for energy supplying and management. Smart Grids topology in form of energy management has forced power supplying agencies to become globally competitive. Demand Response (DR) Programs in context with smart energy network have influenced prosumers and consumers towards it. In this paper Fair Emergency Demand Response Program (FEDRP) is integrated for managing the loads intelligently by using the platform of Smart Grids for Residential Setup. The paper also provides detailed modeling and analysis of respective demands of residential consumers in relation with economic load model for FEDRP. Due to increased customer’s partaking in this program the load on the utility is reduced and managed intelligently during emergency hours by providing fair and attractive incentives to residential clients, thus shifting peak load to off peak hours. The numerical and graphical results are matched for intelligent energy management scenario.
Advancement in Wide Area Monitoring Protection and Control Using PMU’s Model in MATLAB/SIMULINK  [PDF]
Waheed Ur Rahman, Muhammad Ali, Amjad Ullah, Hafeez Ur Rahman, Majid Iqbal, Haseeb Ahmad, Adnan Zeb, Zeeshan Ali, M. Ahsan Shahzad, Beenish Taj
Smart Grid and Renewable Energy (SGRE) , 2012, DOI: 10.4236/sgre.2012.34040
Abstract: A big step forward to improve power system monitoring and performance, continued load growth without a corresponding increase in transmission resources has resulted in reduced operational margins for many power systems worldwide and has led to operation of power systems closer to their stability limits and to power exchange in new patterns. These issues, as well as the on-going worldwide trend towards deregulation of the entire industry on the one hand and the increased need for accurate and better network monitoring on the other hand, force power utilities exposed to this pressure to demand new solutions for wide area monitoring, protection and control. Wide-area monitoring, protection, and control require communicating the specific-node information to a remote station but all information should be time synchronized so that to neutralize the time difference between information. It gives a complete simultaneous snap shot of the power system. The conventional system is not able to satisfy the time-synchronized requirement of power system. Phasor Measurement Unit (PMU) is enabler of time-synchronized measurement, it communicate the synchronized local information to remote station.

Abstract: Breast feeding provides complete and balanced nutrition to the baby. The survey done in 1995 by health ministry,Pakistan reported that although 94 % of the children were ever breastfed, only less than 16 % of the children were exclusively breastfed.Objective: To assess the knowledge, attitude and practices regarding breastfeeding among undergraduate students of medical colleges ofKarachi. Materials and Methods: Data Source: Female medical students from Clinical and preclinical years. Study Design: Cross sectionalstudy. Setting: Liaquat National Medical College (LNMC) and Sir Syed College of Medical Sciences (SSCMS), Karachi. Period of study: 3months. Material and Methods: Total 222 female students filled a multiple choice semi-structured questionnaire. Results: Out of total 222female students 32.9% were in pre-clinical group while 67.1% were in clinical group. It was observed that educational level of the student wasstrongly associated with the knowledge regarding initiation of breastfeeding and age till which exclusive breastfeeding should be continued(p=0.000). Clinical group had more knowledge regarding colostrums as compare to the pre-clinical group (p=0.000). Conclusions: A significantdifference was found between preclinical and clinical students regarding the knowledge of breastfeeding. In this study most students were fromclinical level of undergraduate medical education which made them more aware regarding the significance of breastfeeding.
Acute Cholecystitis Mimics Ischemic Cardiac Disease: A Case Report and Review of the Literature  [PDF]
Osman Habeeb, Taj Eldeen Ebrahim
Case Reports in Clinical Medicine (CRCM) , 2014, DOI: 10.4236/crcm.2014.311131
Abstract: Chest pain and shortness of breath are typical indicators of cardiac problem and may lead to life threatening conditions. Nevertheless, these symptoms may also be associated with a non-cardiac condition clinically such as cholecystitis. We have reported 4 cases in a period of 6 months wherein the patients presented with cardiac-like symptom show ever; they were subsequently diagnosed with non-cardiac problems. Two patients presented with severe chest pain and shortness of breath mimicking angina pectoris. They were admitted to the intensive care unit for emergency management. The ECG findings were normal. There were two other patients who also presented with severe chest pain and shortness of breath with ST segment elevation during the ECG examination. The abdominal ultrasound in all the 4 patients showed typical features of acute calculus cholecystitis. All patients were young (30 - 36 years of age) females who were obese (BMI ranging from 30 - 34). Cholecystectomy was performed which led to improved symptoms postoperatively and ECG changes became normal.

Abstract: Pakistan has been full of surprises since its inception. Although contrary to Jawaharlal Nehru’s predictions, Pakistan did not disintegrate and merge with India “six months” after its emergence, but within twenty-five years of its existence, it lost its eastern wing (East Pakistan), which emerged as Bangladesh; and within another two decades, the country became one of the most ungovernable and dangerous places in the world. In view of its checkered history of unpleasant surprises for the country itself, its neighbors and others, one can take unpredictability as the main variable for Pakistan. The country went through thirty-two years of military rule and other thirty-odd years of authoritarian, oligarchic democracy, a democratically elected government completed its full-term and was succeeded by another in May 2013 in its history. One may assume that Pakistan will functionally remain a democracy, albeit under the waning influence of the military and “feudal” aristocracy. Whether Pakistan remains an Islamic “garrison state”, a civilian “illiberal democracy”, or transforms itself into a liberal democracy in the coming years are important questions today. However, it appears that in the coming years the Pak-US relationship will remain as awkward and unpredictable as it has been since the US-led invasion of Afghanistan in 2001. Pakistan’s identity crisis – “the mother of all conflicts”, to one scholar – is reflected in the state-sponsored Islamization process and the country’s hovering between civilian and military rule.
Weak-Coupling Limit. I A Contraction Semigroup for Infinite Subsystems
David Taj
Physics , 2009,
Abstract: We consider the class of quantum mechanical master equations defined on a generic Banach space, arising by projecting weakly perturbed one-parameter groups of isometries. We show that the possible semigroup approximations are far from unique. However, uniqueness can be reestablished through the introduction of a dynamical time averaging map. The generator of the resulting Contraction Semigroup is always well defined, irrespective of the dimensions of the projected subspace, and of the spectral properties of its free dynamics. We show how our approach includes and generalizes the preexisting literature.
Weak-Coupling Limit. II On the Quantum Fokker-Planck Equation
David Taj
Physics , 2009,
Abstract: In a recent work we have found a contraction semigroup able to correctly approximate a projected and perturbed one-parameter group of isometries in a generic Banach space, in the limit of weak-coupling. Here we study its generator by specializing to $W^*$-algebras: after defining a Physical Subsystem in terms of a completely positive projecting conditional expectation, we find that it generates a Quantum Dynamical Semigroup. As a consequence of uniqueness and strong generality (well defined dynamics, irrespective of the Physical Subsystem spectral properties or dimensions), its generator deserves to be referred as "the" Quantum Fokker-Planck Equation. We then provide important examples of the limit dynamics, one of which constitutes a new Quantum generalization of the celebrated Fermi Golden Rule.

The South-Western Alboran Earthquake Sequence of January-March 2016 and Its Associated Coulomb Stress Changes  [PDF]
Fida Medina, Taj-Eddine Cherkaoui
Open Journal of Earthquake Research (OJER) , 2017, DOI: 10.4236/ojer.2017.61002
Abstract: We expose the results of the study of the south-western Alboran seismic sequence of January-March 2016 and the stress perturbations it caused by means of Coulomb modeling. The use of data from numerous stations allowed us to relocate the largest events (Mw ≥ 3.8) south of those determined by IGN (Spain). The main shock of 25 January 2016 (Mw = 6.3) was relocated at 35.6133°N × 3.6888°W, at a hypocentral depth of 15.5 ± 6.0 km. The epicenters are aligned along two distinct clusters: The first runs N-S towards the Moroccan coast along Al-Idrissi fracture zone, while the second is centered on the Alboran ridge northern thrust fault. The focal mechanisms determined by different agencies correspond to a strike-slip/normal/reverse motion in the western cluster and thrusting in the eastern one. Coulomb stress change modeling shows that the main earthquake: (1) may have been triggered by stress accumulation by the 1994 and 2004 earthquakes; (2) has induced stress perturbations that provide a suitable explanation for the distribution of the aftershock clusters, including the eastern cluster. The prediction of the next event shows that it is likely to occur near the Moroccan coast.
Growth, Physiological and Molecular Responses of Cotton (Gossypium arboreum L.) under NaCl Stress  [PDF]
Sameera Hassan, Muhammad Bilal Sarwar, Sajjad Sadique, Bushra Rashid, Beenish Aftab, Bahaeldeen Babiker Mohamed, Tayyab Husnain
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.55075

Salinity is one of the most serious growth limiting factor, therefore, no longer being ignored. Although, cotton is fairly salt tolerant; its sensitivity at crop stand and yield is affected. This study is planned to identify the growth, physiological and molecular parameters in local cotton varieties FDH 171 and FDH 786 under NaCl stress. There was 100% seed germination but hypocotyl length was reduced at increasing level of NaCl. Plant height, fresh and dry biomass were reduced as the plants were subjected to increased stress of NaCl. Stomatal conductance, transpiration and photosynthetic rate and ionic imbalance were found to be reduced under the gradual increase in NaCl stress and affected the plant’s overall physiological processes. PCR product of AtNHX3 has been identified in stressed and non-stressed plants. Thus, the genotypes FDH 171 & FDH 786 were found tolerant to adoption of salt stress and could be used as a source in crop improvement.
